Typhoid fever is a waterborne disease. There are a reported 16 million illnesses and 600,000 deaths annually (Crump, 2010). Most cases occur in developing countries; however, citizens of developed countries who visit developing ones are at risk of catching this disease (CDC, 2013). The disease is caused by Salmonella typhi, which infects the lymph nodes, necessary for immune response. Basic symptoms include a prolonged fever, interruptions in proper bowel function (constipation and diarrhea), severe cough, and in some cases, rose-colored spots on the patient. Salmonella typhi is a gram-negative bacteria that can only be carried by humans. There is also a similar, but less deadly form of this pathogen named Salmonella typhimurium (WHO, 2003).
